Description

Technical Field

[0001] The present invention relates to the technical field of coal mine safety production, and specifically to an intelligent monitoring device for a coal conveying belt. Background Art

[0002] The basis for the operation and power generation of a thermal power plant is coal combustion. Therefore, the normal operation of the coal conveying system is the prerequisite and guarantee for the normal operation of the thermal power plant. Coal conveying is often carried out continuously by means of a conveyor belt. Compared with other operating systems of a thermal power plant, the operating environment of the fuel transportation system is relatively harsh, the operating work line is relatively long, and the equipment structure is relatively simple. Therefore, it is extremely easy to be ignored during work, and it is very easy to breed some potential safety hazards;

[0003] Since the coal quality conditions in different regions are not the same and the environmental gaps in coal conveying workshops are relatively large, in existing power plants and coal yards, the coal conveying system mostly adopts a remote system for control, and a perfect video monitoring system is correspondingly installed. For example, both Patent CN114803385A and CN217846121U mention the use of laser detection to monitor the condition of the belt itself, and an alarm is issued for processing after abnormal data is found. Although this processing method can monitor and process the abnormal area of the belt in a timely manner, it cannot effectively distinguish the abnormal data part, and it is impossible to confirm on-site whether it is a problem with the belt itself or interference from the external environment. Its method of issuing an alarm and notifying the manual to perform on-site processing undoubtedly increases the handling time of the crisis, increases the damaged time and damage degree of the continuous operation of the conveyor belt, is prone to safety accidents due to the fracture of the coal conveying belt, and reduces the emergency handling ability and the intelligent level of safety production of the power plant. Summary of the Invention

[0035] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0036] An embodiment of the present invention provides a coal conveyor belt intelligent monitoring device, which solves the problem that the monitoring method is difficult to monitor the damage of the conveyor belt in real time and give an early warning, reducing the emergency handling ability of the power plant and the intelligent level of safe production.

[0037] As Figures 1 to 13As shown, a preferred embodiment of the present invention proposes an intelligent monitoring device for a coal conveyor belt, comprising a track frame 1, a conveyor belt 2, a conveyor roller 3 and a detection component, wherein the conveyor belt 2 and the conveyor roller 3 are both mounted on the track frame 1, and the conveyor roller 3 is in rolling contact with the conveyor belt 2, the detection component is mounted in the track frame 1, and the detection component includes two visual monitoring components with the same structure and function, wherein the area close to the unloading point of the conveyor belt 2 is set as a first visual monitoring component 4, and the area away from the unloading point of the conveyor belt 2 is set as a second visual monitoring component 5, the first visual monitoring component 4 and the second visual monitoring component 5 both include a laser and a camera for detecting belt tearing, the laser in the first visual monitoring component 4 emits a light beam pointing to the front of the conveying surface of the conveyor belt 2, and the laser in the second visual monitoring component 5 emits a light beam pointing to the back of the conveying surface of the conveyor belt 2, and the laser is directed toward the conveyor belt 2. A laser is emitted, which is collected by the camera after being reflected on the surface of the conveyor belt 2, and the center of the laser stripe is automatically extracted. The height and depth parameters of the cross section of the conveyor belt 2 are analyzed through the laser stripe patterns and light reflection parameters collected by the host. When the surface parameters of the conveyor belt 2 are detected to be abnormal, the conveyor belt 2 is controlled to stop for processing. A third visual monitoring component 10 for detecting the conveying and stacking conditions of the coal gangue is installed at the top position of the coal gangue conveying channel. In addition, it also includes a lifting roller 6, which is rotatably installed in the track frame 1. The lifting roller 6 is corresponding to the conveying roller 3. The lifting roller 6 is located below the conveying roller 3 and the lifting roller 6 is in rolling contact with the conveying surface of the conveyor belt 2. The lifting roller 6 is provided with a insertion slot 61 for inserting bristles. The first visual monitoring component 4, the second visual monitoring component 5 and the third visual monitoring component 10 share a set of edge algorithm hosts.

[0038] During operation, the third visual monitoring component 10 is used to monitor in real time the accumulation height of the coal gangue transported on the upper part of the conveyor belt 2. The second visual monitoring component 5 is used to detect the belt deformation and belt tearing condition of the conveyor belt 2 when it carries coal gangue. The first visual monitoring component 4 is used to detect the belt tearing condition of the conveyor belt 2 when it is unloaded after unloading. The main engine comprehensively judges the data collected by the first visual monitoring component 4, the second visual monitoring component 5 and the third visual monitoring component 10 to judge the belt tearing condition of the conveyor belt 2. In order to avoid the recognition error caused by the adhesion of coal gangue dust, the lifting roller 6 is used to continuously clean the coal gangue bearing surface of the conveyor belt 2 during operation, thereby eliminating errors and improving the stability of the monitoring of the operation condition of the conveyor belt 2.

[0039] Machines are used to replace human eyes to measure and judge, so that what you see is what you know. A large amount of real scene image data is automatically received and intelligently analyzed and processed to achieve the positioning, detection, measurement, identification and judgment of objects. Through "perception intelligence + data processing and analysis + decision-making judgment", identification is done first and then judgment is made, and abnormal situations are actively warned.

[0040] Further, such asFigure 4 and Figure 5 As shown in Figure 5 , waist-shaped grooves are provided at the positions of the support rods of the track frame 1. A dust reduction block 11 is slidably installed in the waist-shaped grooves, and a dust reduction spring 12 is connected between the dust reduction block 11 and the track frame 1. A dust reduction rod 13 is fixedly installed on the dust reduction block 11. The dust reduction rod 13 is located at the end of the lifting roller 6, and the dust reduction rod 13 extends obliquely to both sides of the lifting roller 6 in a "V" shape.

[0041] To further improve the dust removal effect on the surface of the conveyor belt 2, during operation, the dust reduction block 11 is kept at a predetermined staying height on the track frame 1 under the elastic support of the dust reduction spring 12. At this time, the dust reduction rod 13 maintains a predetermined fitting distance from the surface of the conveyor belt 2. When the conveyor belt 2 travels to this area, the dust removal effect is achieved through the blocking action of the dust reduction rod 13.

[0042] Further, as Figures 3 to 5 shown, multiple groups of the dust reduction rods 13 are provided. A pair of dust reduction rods 13 in the same group are respectively located at the two end positions of the same lifting roller 6 and have opposite inclination directions. The multiple groups of dust reduction rods 13 are arranged in sequence along the conveying direction of the conveyor belt 2, and the distances between the multiple groups of dust reduction rods 13 and the surface of the conveyor belt 2 decrease in sequence in the direction away from the coal gangue feeding point. Annular bands are spirally wound on the surfaces of the dust reduction rods 13.

[0043] The multiple groups of dust reduction rods 13 provided gradually approach the surface of the conveyor belt 2 in a gradually increasing height manner, thereby achieving the effect of gradually cleaning large-particle attached coal gangue. Through the inclination of the installation posture of the dust reduction rod 13 itself, while blocking and cleaning dust or particles, the cleaning object can be gradually transferred from the central position of the conveyor belt 2 to the edge position, thereby reducing the accumulation of dust or particles at the bottom of the track frame 1 during the dust removal operation and avoiding secondary pollution. Through the spirally wound annular bands, the peeling and cleaning effect on adsorbed stubborn particles is improved.

[0044] Further, as Figure 6 、 Figure 9 and Figure 10 shown, a rectangular frame-type repair bracket 7 is fixedly installed in the middle of the track frame 1. The repair bracket 7 is located between the first visual monitoring component 4 and the second visual monitoring component 5, and the return section of the conveyor belt 2 passes through the repair bracket 7. An elastic strap 71 is fixedly installed in the middle of the repair bracket 7. The strap 71 is located above the return section of the conveyor belt 2, and thickened gaskets 72 are evenly arranged on the strap 71.

[0045] When the second visual monitoring component 5 detects that the belt condition of a certain section of the conveyor belt 2 is abnormal, the host marks the position of this area and records its running and conveying distance. When the conveyor belt 2 in this area completes the unloading operation and passes through the area of the lifting roller 6, the cleaning operation of the dust or particles on the belt surface is realized through the dust removal effect of the bristles on the lifting roller 6 and the dust removal rod 13. Subsequently, the conveyor belt 2 continues to run and passes through the position of the first visual monitoring component 4. The first visual monitoring component 4 performs secondary detection on the marked abnormal area on the conveyor belt 2, compares the previous detection results of the second visual monitoring component 5, and judges the tearing condition of the belt of the conveyor belt 2. Subsequently, when the conveyor belt 2 in this area runs to the repair bracket 7, the host stops the machine and sends staff to conduct on-site inspection and maintenance operations. During the maintenance period of the staff, by pulling the strap 71 to make it deform away from the conveyor belt 2 and then releasing it, the strap 71 returns to its original shape and forms a slapping effect on the surface of the conveyor belt 2, thereby driving the conveyor belt 2 to vibrate, and realizing the precise dust removal operation of the abnormal tearing area on the surface of the conveyor belt 2 through the inertial effect. The provided gasket 72 can improve the oscillation effect when slapping the conveyor belt 2 and reduce the residue of dust.

[0046] Further, as Figures 6 to 10 shown, a plurality of follower columns 9 are rotatably installed on the track frame 1, and the plurality of follower columns 9 are distributed around the repair bracket 7. A follower rod 91 is slidably installed on the follower column 9. A sawtooth groove 14 is provided on the track frame 1, and the end of the follower rod 91 is engaged with the sawtooth groove 14 in an inclined state. A follower cylinder 92 is jointly installed between two relatively installed follower rods 91. The follower cylinder 92 is located above the return section of the conveyor belt 2. An air groove 93 is opened on one side of the follower cylinder 92 facing the repair bracket 7. A valve port 94 communicating with the air groove 93 is provided on the follower rod 91. A light band 75 is fixedly installed on the repair bracket 7.

[0047] During the process of the maintenance operation of the conveyor belt 2 by the staff, after removing dust from the surface of the conveyor belt 2 using the strap 71, the light belt 75 is lit to illuminate the maintenance area through the light belt 75. Subsequently, the follower cylinder 92 is pulled to slide above the conveyor belt 2, and air is pumped through an external air pump to the valve port 94, thereby creating a negative pressure in the air groove 93 to achieve dust suction treatment in the maintenance area of the conveyor belt 2, improving the cleanliness of the maintenance space for the staff and enhancing safety. In addition, by the irradiation of the light belt 75, the maintenance personnel can judge the tearing direction and tearing area of the belt according to the light-transmitting area on the conveyor belt 2, so as to achieve a complete replacement or repair operation. When the preliminary dust suction treatment is completed, the staff rotates the follower rod 91 to move it in an inclined posture towards the coal conveying section of the conveyor belt 2 until it fits with the conveyor belt 2. Subsequently, the bottom of the follower rod 91 is clamped to the corresponding position. At this time, the bottom support effect on the conveying section of the conveyor belt 2 is achieved through the follower rod 91 and the follower cylinder 92, and during the support, continuous dust suction operation in the maintenance area is carried out. Through the bottom support, the work safety and stability of the maintenance area can be improved, and the accidental vibration during the maintenance operation can be avoided to prevent the falling of coal gangue.

[0048] Further, as Figure 6 、 Figure 7 and Figure 9 shown, the middle part of the repair bracket 7 is symmetrically installed with repair plates 8 by means of hinges. The repair plates 8 are located below the return section of the conveyor belt 2. The two ends of the repair bracket 7 and the two ends of the repair plates 8 are symmetrically provided with jacks, and pins 81 are slidably installed in the jacks of the repair plates 8. The middle part of the repair bracket 7 is fixedly installed with an elastic diaphragm 73. The diaphragm 73 is located between the two repair plates 8, and the lower half of the diaphragm 73 is arc-shaped and abuts against the side wall of the repair plate 8. The inclination angle of the repair plate 8 at its hinged position is kept within the range of 0 to 45 degrees. A fitting strip 82 is arranged at the end of the repair plate 8. When the repair plate 8 is in the horizontal position, the fitting strip 82 is in contact with the front surface of the conveying surface of the conveyor belt 2. A pressing plate 74 matched with the fitting strip 82 is arranged at the end of the repair bracket 7, and the pressing plate 74 is in contact with the back surface of the conveying surface of the conveyor belt 2. The fitting strips 82 are arranged at intervals at the end of the repair plate 8, and an arc-shaped groove sunken downward is arranged in the middle of the fitting strip 82.

[0049] Under normal operating conditions, the repair plate 8 stays in the repair bracket 7 in an inclined posture. When maintenance operations need to be carried out on the conveyor belt 2, the repair plate 8 is rotated by the staff to make it enter the horizontal state, so as to support the bottom of the conveyor belt 2. Subsequently, the horizontal posture of the repair plate 8 is fixed by the bolt 81. At this time, under the clamping action of the fitting strip 82 and the pressing plate 74, the conveyor belt 2 in the area of the repair bracket 7 is in a static state and its position is relatively fixed. Then, the staff repairs or replaces the conveyor belt 2 in this area. During this process, the repair plate 8 acts as a repair workbench, providing a flat support during the repair of the conveyor belt 2 and improving the convenience of maintenance operations.

[0050] Further, as Figure 9 and Figure 11 shown, a through notch is formed in the middle of the repair plate 8, and a shaping plate 83 is slidably installed in the notch. A U-shaped plate 84 is fixedly installed on the side of the repair plate 8 away from the conveyor belt 2. A rotating rod 85 is installed on the U-shaped plate 84 by means of thread fit, and the end of the rotating rod 85 is rotatably connected to the shaping plate 83. A pointing rod 86 is slidably installed on the U-shaped plate 84, and the end of the pointing rod 86 is fixedly connected to the shaping plate 83.

[0051] To further highlight the range of the torn area of the conveyor belt 2 and simulate the collapse situation under the ballast of coal gangue, when the repair plate 8 is horizontally unfolded, the staff turns the rotating rod 85. Under the action of the thread, the rotating rod 85 pushes the shaping plate 83 to protrude and extend upward from the repair plate 8, and through the contact with the conveyor belt 2, a collapse deformation similar to the state of coal gangue accumulation is generated in the middle area of the conveyor belt 2, thereby highlighting the range and direction of the torn area, which is more conducive to the judgment of the operator and the subsequent repair process, improving the convenience, and also improving the overall efficiency and stability of the operation and maintenance of the coal conveyor belt.

[0052] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments.
